Abstract: Validating microprocessor instruction execution by receiving a floating-point exception selection, receiving a validation method selection, generating validation data according to the floating-point exception selection and the validation method selection by randomly generating a first tensor element value and randomly generating a second tensor element value according to the first tensor element value and the floating-point exception selection, and executing a floating-point computation according to the validation data.

Abstract: A method of automatically defining a new class in a class hierarchy includes creating a descendent class that descends from one or more specified ancestor classes; sequentially analyzing each class along each inheritance path from the specified ancestor classes to a specified similar class to identify each class item in each class that is not selected from the specified ancestor classes; storing a respective pointer for each class item identified in each class that is not inherited by the class referencing the class item and associated with the class; storing a respective pointer for each class item identified in each class that is inherited and redefined by the class referencing the class item and being associated with the class if a pointer referencing the class item is not already stored; and copying each class item referenced by a stored pointer to the descendent class.

Abstract: A synchronization method including running (10) a system (725) having multiple agents (730) in parallel operation and forcing synchronization order (20, 30, 40, 50) between the multiple agents at at least one intervention juncture. Preferably, the multiple agents (730) include at least two agents (570, 590) accessing a single address at almost the same time. Further preferably, the forcing step includes forcing a predetermined one (570) of said two agents to access said address before the other one (590) of said two agents accesses said address.

Abstract: A synchronization method including running a system (725) having multiple agents (730 and 780) in parallel operation, the multiple agents each having at least one path (732) to a common bus (734). A bus arbitration mechanism (728) is used to synchronize between said multiple agents in accordance with a predetermined scheme, including blocking (310) at least one individual agent's path to the common bus (734) if said scheme indicates (315) that said individual agent is not to be activated, and restoring (320) said at least one individual agent's path (730) to the common bus (734) once said scheme indicates that said individual agent (730) can be activated.
